Abstract

Procédé de détermination de la vitesse de rotation du turbocompresseur d'un moteur à combustion interne de véhicule automobile, éventuellement muni d'au moins un circuit de recirculation partielle des gaz d'échappement à haute pression piqué entre le collecteur d'échappement et le collecteur d'admission. Le procédé comprend les étapes suivantes: on détermine un vecteur des mesures accessibles comprenant la mesure de la pression avant turbine, de la pression dans le collecteur d'admission et éventuellement de la pression après l'échangeur thermique EGR, on détermine l'écart entre le vecteur des mesures accessibles et le vecteur des mesures accessibles correspondant issu d'un observateur, on détermine un vecteur des dérivées temporelles des variables observées en fonction de l'écart entre le vecteur des mesures accessibles et le vecteur des mesures accessibles correspondant issu de l'observateur, et on détermine un vecteur des variables observées par intégration du vecteur des dérivées temporelles des variables observées, le vecteur des variables observées comprenant des valeurs observées correspondant aux valeurs du vecteur des mesures accessibles et la vitesse de rotation du turbocompresseur.Method for determining the rotational speed of the turbocharger of an internal combustion engine of a motor vehicle, optionally equipped with at least one partial recirculation circuit of the high-pressure exhaust gases stitched between the exhaust manifold and the collector intake. The method comprises the following steps: a vector of the accessible measurements comprising the measurement of the pressure before the turbine, of the pressure in the intake manifold and possibly of the pressure after the EGR heat exchanger is determined, the difference between the vector of the accessible measurements and the corresponding accessible measurements vector from an observer, a vector of the time derivatives of the observed variables is determined as a function of the difference between the accessible measurement vector and the corresponding accessible measurement vector resulting from the observer, and determining a vector of the variables observed by integration of the vector of time derivatives of the observed variables, the vector of the observed variables comprising observed values corresponding to the values of the vector of the accessible measurements and the speed of rotation of the turbocharger.
